This invention relates to manifolding devices, which are especially adapted for use in connection with continuous fanfolded forms.

Heretofore fanfolded forms could not be used 5 satisfactorily on typewriters, unless they were interleaved with long continuous transfer strips because of the difficulty encountered in attempting to insert reusable transfer sheets while the forms are threaded through the machine. The term fanfolded as used in this application refers to those continuous forms, which are folded longitudinally adjacent their edges, so as to form a Zigzag shape in the transverse section.

To utilize reusable transfer sheets, it has been regarded as necessary to slit the forms along the longitudinal edges at the factory, so as topermit the movement of the forms with reference to the transfer sheets, whenever it is necessary to tear off a set of forms on which the writing operation has been completed. The slitting of the forms at the factory not only is an extra operation, but necessitates careful handling to maintain the sheets in registration until they are ready for use.

An object of the present invention is to provide a device which operates to slit a fanfold form, While it is being moved through a typewriter machine, and to incorporate the slitter with the transfer sheets, so as to effect a slitting operation, whenever the operator moves the forms through the machine sufliciently far to tear off a used set.

Referring now to the drawings, Fig. 1 illustrates a top plan view of a transfer pack embodying my invention; Fig. 2 is a bottom view of the pack shown in Fig. 1; Fig. 3 is a side elevation of the pack in use in a typewriter; Fig. 4 is a view on an enlarged scale showing the relative position of the manifold form and the transfer pack during use, while Figs. 5, 6 and '7 are sections taken on the correspondingly numbered lines in Fig. 4.

The transfer pack which embodies my invention is illustrated, as having a plurality of transfer sheets 10, which are arranged in superimposed overlapping relationship, and which are connected together at the adjacent corners of one end, so as to provide pockets through which some of the forms may be threaded. In the arrangement illustrated, the sheets are provided with tabs 11, which project laterally beyond the longitudinal edges thereof, and the tabs are connected together in any desirable manner, such as by stitching 12. Flexible strips 13 are also attached to the tabs, and the free ends are adapted to be looped over a bar 14, as is shown in Fig. 3. The strips are sufiiciently long to allow a set of forms to be typed before the slack is sufficiently taken up, At

such time, the forms may be drawn past the transfer sheets until a new set is available for use. The platen 15 may then be turned backwardly until the top of the new set is in position for typing, and the used set may thereafter be torn off.

To permit the use of a fanfolded form, I have provided a slitter across one edge of each transfer sheet. In the preferred form, the slitter comprises a narrow strip of flexible, yet rigid material, such as celluloid, that presents sharp edges to the forms, as they are passed through the machine. In addition each strip has a notch 59, which is disposed near the ends thereof, and in the path of travel of the longitudinal folds of the forms. The ends of the strips extend across the tabs, and are rigidly bound together with them to form a unitary structure. That portion of each strip in contact with its associated sheet is firmly cemented to the sheet.

To use the device embodying my invention, the first set of forms 25 is slit by hand along the lon gitudinal edges 26, and the set is threaded through the pack. Thereupon, the ends of the strips are looped over the bar 14 that is movable with the typewriter carriage, and that is spaced sufiicient- 1y close to the platen to provide enough slack in the strips for typing one set of forms, and for enabling it to be moved through the machine until the bottom edge of the transfer pack is slightly above the center of the platen roller. In such position, the ends of the forms can be gripped to the exclusion of the transfer sheets and pulled through the machine. During this movement, the strips 13 are taut, and as a result, the forms are moved with reference to the pack. Moreover,

during such movement the notched cutting edges of the strips 20 slit the'longitudinal folds, and thus enable the transfersheets to remain in the desired relationship with reference to the new set of forms. When a new set has been brought into registration with the transfer pack, the platen rotation is reversed until the top of the form is in position for typing, and the used set is torn off. Thereafter, the operation is repeated until each set of forms is used.

My invention has made possible the use of a continuous fanfolded form in a typewriter, or other business machine, without requiring the use of long interleaved continuous transfer strips, which are known to thetrade as one-time carbons. Thus, I have been able to retain the desired registration of the forms until they are ready for use, and I have made available reusable carbons for such purpose.
